light can travel through a vacuum whereas sound cant
No, sounds cannot travel through a vacuum. This is because sound requires a medium to travel through because it requires the vibration of particles to travel and there need to be particles to vibrate for it to travel through.
Sound wave do not travel through vaccum as it need medium to travel.
Sound waves travel through matter, whether solid, liquid, or gas. They do not travel through vacuum.
The Pharnycx
The larynx is only the passageway for air, as it is covered by the epiglottis to prevent food from entering it during swallowing. The pharynx, however, serves as a passageway for both food and air.
which process moves food through pharynx
They pass through mouth to the pharynx which is connected with trachea
Food does pass through the pharynx before it goes into the esophagus and on to the stomach.
Swallow
Nares, nasal cavity, pharynx, larynx, trachea, bronchus, bronchioles, alveoli
The food enters the pharynx, then through the esophagus, then acts as a passageway between the pharynx and the crop. Then it goes through the gizzard.
The pharynx serves as a passageway for both food and air.
The main function of the pharynx is to provide a passageway for the respiratory and digestive tracts. The pharynx is also referred to as the throat. It houses the tonsils, the uvula, epiglottis and is the entrance way to the esophagus. The pharynx or throat, allows common passageway for air into your lungs and food into your stomach. The pharynx has two roles. The upper part of the pharynx will only allow food to pass through, and the lower part of the pharynx allows air, fluids, and food to pass through.
Pharynx is the part of the throat that is common to both digestive system andrespiratory system. It starts behind the nose and ends in the beginning of the voice box (larynx) and the oesophagus. It is a muscular tube lined by mucous membranes that connects the nose with the wind-pipe (trachea) and the mouth with the food-pipe (esophagus) and thus acts as a common passage for both food and air. Structure of Pharynx: Pharynx is a soft collapsible tube. It is about 13 cm long in humans and lies in the front of the spinal column. The pharynx contains tonsils and adenoids (in children). Pharynx is divided into three parts namely the oropharynx, nasopharynx and laryngopharynx. Functions of Pharynx: The main function of pharynx is to act as a common passage for both food and air. Thus the pharynx should channel food without choking. Pharynx plays a major role in the first phase of swallowing. As the food bolus is pushed by the tongue into the pharynx, it pushes the food down by muscular contraction down the esophagus. The other important function of Pharynx is to equalize pressure that gets built near the ear drums. This is made possible by the two eustachian tubes (one from each ear) that connect the middle ear with pharynx. Pharynx is very soft and can be easily collapsed. Thus any physical structure can cause an obstruction in the pharynx. Pharynx is easily susceptible to infections. The inflammation or infection of pharynx is known as pharyngitis which is caused by micro organisms that enter through nose or mouth. The pharynx might collapse during sleep and the resulting condition is known as Obstructive Sleep Apnea (OSA). Any failure in the normal functioning of pharynx can cause breathing, swallowing or voice problems.
